Problems importing JAI in Eclipse

I'm trying to use the following import in Eclipse running on Mac OS X 10.6:

import javax.media.jai.JAI;

Unfortunately, this doesn't work, instead I get the following message:

"Access restriction: The type JAI is not accessible due to restriction on required library /System/Library/Java/Extensions/jai_core.jar"

How can this be resolved? I want to use JAI.create("fileload", "filename");

The file permissions in the folder Extensions:

A quick fix can be found here: http://lkamal.blogspot.com/2008/09/eclipse-access-restriction-on-library.html (However, it's more of a work-around...)

You might check file's the permissions. Here's what 10.5 looks like:

$ ls -l /System/Library/Java/Extensions/jai_core.jar
-rw-r--r--  1 root  wheel  1893836 May 31  2008 /System/Library/Java/Extensions/jai_core.jar

Fixed my issue with JAI by removing the JRE System Library from the build path and then re-adding it. This fix is based on the solution provided here.
